Passing arrays to a javascrpt

[popeye]

Based on which option selected in the first dropdown <select> menu, I need to change the option list of the second <select> dropdown menu.
I need this to be able to collect and/or change State and County information using <select> and dropdown menus.
Is it possible to pass back and forth a php created array to a javascript function used with onchange property of <select>?

Thanks.

yes that is possible,
only thing is u need to populate javascript arrays for all the options.
then using javascript populate the select list based on the array[javascript] and your condition.
